PATENT AUTOMATIC COLOR-PRINTING MACHINE FOR PRINTING YARNS, 8L0.

SPECIFICATION forming part of Letters Patent No. 728,225, dated May 19, 1903.

Application filed October 23,1900. Serial No. 34,092. (No model.)

T0 on whom it may concern:

Be it known that I, OTTO HALLENSLEBEN, asubject of the King of Prussia, German Emperor, and a resident of Hilden, in the Province of the Rhine, German Empire, have invented a new and useful automatic colorprinting machinefor printing yarn used in the manufacture of carpets, plush, or pile goods for upholstery and similar fabrics, of which the following'is an exact specification.

The object of this invention is to construct a machine which shall print the colors, which appear in the design, upon yarns used in the manufacture of carpets, plush, or pile goods for upholstery and similar fabrics in such manner that when the several threads have been placed side by side and interwoven the said printed colors shall form the desired pattern. In such a case each separate thread by itself must necessarily be printed with the colors required by that particular thread. As, however, itwould'take too much time and be too costly to treat each separate thread by itself, a large number of threads are stretched side by side from which a corresponding number of carpets are produced. Machines in several forms already exist which have been constructed for this purpose, and in one such the yarn to be printed is wound upon a drum which is thereupon turned by hand in such a manner that the printing apparatus takes efi'ect or is put into action at the desired spots. In another form, however, the yarn is stretched in long, lengths and i then the printing is performed by the forward movements of a carriage and the laying on of the colors, the whole operations, however, being performed by hand,

As a general fundamental principle or, say, the leading idea in the invention of the machine which forms the subject-matter of this specification the following must be considered. The whole of the operations or, say, processes which the yarn has to pass through up to the weaving-that is to say, the printing, steaming, and washing-follow automatically. This general fundamental principle is attained in my improved apparatus by mechanical arrangements, which each in turn work entirely automatically.

The advantages or, say, the technical re- .to receive a new color.

sults which this machine affords are the following:

First. The operation of the printing-carriage is attained mechanicallythat is to say, the carriage, which'is provided with two complete sets of gearing, the one for traversing and the other for printing, is positioned at the requiredspots by a mechanism governed by a jacquard machine, whereby the traversing gear is uncoupled and the printing-gear coupled up. The carriage then passes on to the next spot to be printed, and these consecutive operations are continued until the end of the printing-bed has been reached, whereupon a reversing mechanism is automatically thrown into gear, so that the carriage returns to its original position Meanwhile the machine has requiredno attention.

Second. The transfer of the yarn which has been colored from the framework, which acts as a support during the printing, to the steaming-truck, as also the transfer of this latter to the steaming apparatus and thence to the washing apparatus, is carried out in such a manner that the yarn is not touched by hand, and thus a smudging of the color is avoided.

Third..'lhe washing apparatus works automatically, and the steaming-truck and the yarn are washed separately, so that naturally the cleansing of both is more perfect.

Fourth. The color required for each length of yarn is measured off by an automatic measuring apparatus. The color is not laid on by asingle roll, in which case the outside threads always receive the most color, but by a series of rolls arranged one behind the other, and the liquid color is laid on the yarn from above. By this means in dealing with expensive colors the material is economized, as each quautity'required is accurately measu red off. Further, the color sinks better into the yarn, is equally distributed, and does not require to be wiped off, as is necessary when the color is laid on from below in order that the color shall not drop.

Fifth. The machine works in duplicatethat is to say, during the printing on one side fresh yarn is being laid on the other side, so that by this means a continuous working can take place.

1 and 5 show a side view of the Whole machine. Figs. 6 and 6 show aplan of the same Fig. '7 is a vertical section through Fig. 5. Figs. 8 to 11 are details.

Referring to Figs. 5, 6, and 7, it will be seen that the arrangement for the stretching of the threads consists of a number of symmetrical standards 1, which are arranged at suitable distances from one another and connected together. On the tops of these standards are mounted in bearings, so as to be capable of being revolved, two shafts 2, running the whole length of the apparatus, upon which shafts are fixed rods 3 at such a distance apart as to correspond with the points of the design. Beneath these rods on either side is arranged a railway 4, upon which prin ting-carriages, to be presently'described, automatically move forward.

The arrangement and mode of working of the printing-carriage are as follows: As will be seen, the stretched yarn lies upon the rods 3, and the distance between any two rods corresponds to the length, say, of a flowerbud. It is therefore necessary to apply a band of color over these threads between each two of the rods 3, and that color must correspond with that which appears at the corresponding point in the pattern. If the pattern, for example, has six colors, then those colors, one after the other, first color No. 1, then No. 2, No. 3, and so on, must be laid on those spots on which they appear in the pattern.- Hence the necessity that the carriage be so arranged as to remain stationary at the proper spots when the laying on of the color follows. For this purpose the carriage is provided with two sets of gearing, one of which serves for the forward movements of the carriage, while the other serves for the printing of the yarn. These two sets of gearing always work separately, so that when the gearing for the forward movement is at work the gearing for the printing is thrown out. The gearing for the forward movement or traversing gearing is set in motion by an endless traveling cord 6, running over cord-pulleys 5, Fig. 5, which are arranged at either end of the printing-machine, the said cord running also over a pulley 7, (see also Figs. 1 and 2,) mounted on the printingcarriage, whereby the pulley 7 is driven, the motion being transmitted by means of spurgear 9 to a spur-wheel 9, which gears with a rack 8. The pitch of the teeth of the rack 8 is arranged so that a given number of teeth (in this case six) corresponds with the distance between two of the rods 3. The proportions of the spur-gear are accordingly so arranged that by one revolution of the pulley 7 the spur-wheel 9 moves around by exactly six teeth. In order that the movement of the printing-carriage may be interrupted and the carriage detained at those points where a certain color is to be laid on, there are a number of pivoted levers or tumblers 10 arranged below the said carriage at the same distance apart from one another as the rods 3, these tumblers normally being turned downward, as those marked 11, Fig. 1, but which can be turned up by strings from the jacquard-machine 12, arranged at one end of the apparatus. The said jacquard-machine, which on account of its well known constrnction is not shown in detail on the drawings, is provided for each color with a card in which these points are cut out at which on the rising of the grid, the corresponding color is to be laid on. The workman having arranged the color and started the jacquard machine the cord-pulley sets the driving-gear in motion and the carriage begins to move forward until it strikes. an erected tumbler 10. At this moment a cam 14: on a lever 13 comes into contact with the said tumbler 10, whereby the lever 13 is raised, in which position it is held fast by a catch 15 on a hanger 16. At the same time the spring 18, arranged on a rod 17, is compressed, wherebypressure is put on the lever 19, so that as the disk continues to revolve the roller on the other end of the lever 19 enters a groove or notch 21 in the saiddisk. Simultaneouslywiththemovement just described a coupling 25, which connects the d riving-gear with the shaft which is driven by the pulley '7, is thrown out of gear by means of a rod pivoted to the lever 19 and the lovers 23 and 24, Fig. 2, so that both the driving-gear and therefore the carriage remain at rest. At this moment the gear which accomplishes the actual laying on the color comes into action. By means of an apparatus about to be described the color is transferred to the rolls and by means of their toand-fro movement is laid on the yarn and distributed thereon by means of pressurerollers on the under side of the yarn. During the movement of the carriage the upper rolls are raised and the under rollers lowered, so that neither can come into contact with the yarn. As soon as, by the above-described arrangement, the carriage is brought to rest through the disengaging of the driving-gear of the carriage, the levers 23 and 24 simultaneously throw a second coupling 26 into gear,thus putting into motion by means of the driving-cord pulley 7 a second train of wheels in the proportions of one to six, and thereby the miter-wheels 27. Upon the shaft of one of these miter-wheels a disk or cam 28 is mounted, having a prominent portion or nose 29, by which a lever 30 has up to this stage been retained in a raised position-that is to IIO say, during the movement of the carriage. As soon as the coupling 26 has been thrown into gear the cam 28 begins to move and the nose 29 leaves its position beneath the roller 31 of the lever 30, whereby the latter drops down and simultaneously presses against the yarn both the lower printing-rolls by means of the lever 33, toothed quadrant 34, and spurwheel 35. At the same moment also a connecting-rod 36, which has so far been resting upon the lever 30, falls down, whereupon a lever 40, caused to vibrate by a connectingrod 39 and a crank 38 on the shaft 37, engages with a notch in the aforesaid connecting-rod 36. By this means-a slide 41, which carries the printing-rolls and which is mounted in V or other suitably shaped guides,is

caused to vibrate, whereby the color is laid on. This vibrating movement continues until the cam 28 has completed a revolution, when the nose 29 again comes under the roller 31 of the lever 30, whereby the lever 30 is raised, the printing-rolls are removed from the yarn, and the connecting-rod 36 raised above the lever 40, so that also the vibration of the slide 41 ceases. At the same time a projection 43 on a cam 42 comes into contact with a projection 44 on the hanger 16, whereby this last, as shown in Fig. 1, is pushed to the right hand, thus releasing the lever 13' from the catch 15, which in falling actuates the lever 19, thus throwing the pririting-gearchine, secures not only a better absorption of the color than has been attained by the lay- -ing on from below, but also at the same time in combination with the automatic measuring off of the required quantity of color(about to be described) secures a pronounced economyin material. The arrangement referred to is as follows: As can be seen from Figs. 1'

and 2, a large color-receptacle 46 is arranged on the top of a standard 45, secured to the printing-carriage, and connected to the said receptacle is a smaller receptacle 47, which by means of a piston 48, which can be raised or lowered by a screw, can be adjusted fora fixed amount of color. In the position shown in Figs. 1 and 2 when the color is being laid on the cook 49 is open, so that the color can flow from the receptacle 46 to the receptacle 47, the outlet-cock 50 being closed. As soon, however, as the printingroll lever 51 is raised, the cam 52 on the same presses the roller 53 upward, whereby the cock 50 is opened and the cook 49 closed by means of the connecting-rod 54 and lever 55, so that the quantity of color in the receptacle 47 can flow into the receptacle 56. When the lever 51 is lowered for the laying on of the color, the upper cook 49 is again opened and the cock 50 closed, while the measured quantity of color which has flowed from the receptacle 47 into the receptacle 56 spreads-itself over a perforated plate 58, arranged above the printing-rollers 57, and thus distributes itself to the said rollers. The lower-roller lever 59 is provided with a pressure-roller 60 for each colorroll 57 which are pressed by springs 61 against the yarn,and therefore against the upper rolls.

At one end of the apparatus is arranged the main driving-gear, which is illustrated on the drawings in detail in Figs. 3 and 4. The frames 62 are provided with wooden joists to which are secured the two jacquard-machines 12, which by means of a tappet or crank movement raise, as described with reference to the printing-carriage, thecorresponding tumblers 10. For this purpose a card is provided for each colorin'a thread, in which such holes are cut as to cause the raising of the lifting-wire in connection with the corresponding tumbler. On the shaft 64 are arranged fast and loose 'pulleys 63 65, so that the said shaft may be set in motion as required. Onthe shaft 64 is also arranged a sleeve 66, which by means of the spur-wheels 67 and 68 and the chain-gear 69 is caused to revolve in a direction opposite tothat of the shaft 64, said sleeve being provided at each end witha coupling-box 7O 70. The shaft 64 is also provided with two couplingboxes 71 71, and between each coupling-box on the said shaft and the coupling-box on the corresponding end of the sleeve'are mounted the cord-pulleys 5 5 for the driving-gear of the printing-carriages, said cord-pulleys being normally loose on the shaft but capable of revolving either to the right or to the left according as to whether they are thrown into gear with the couplings on the shaft 64 or with that on the sleeve 66. Both coupling-box levers are so connected with one'another that either, when either one of the couplings is thrown into gear, theother is shifted to a midposition or both are thrown out of gear. When it is desired to start the printing-carriage, the coupling on the shaft 64 is thrown into gear, and when the carriage has arrived at the end of the railway it strikes against a lever so arranged that the carriage automatically performs the return movement. Thestrikinggear whereby the carriage is caused to move either forward or backward and also to remain at rest is shown in diagram in Figs. Ste 11. Fig. 8 shows the position of the gear while the printing-carriage is at workthat is to say, when the coupling on the shaft isin gear and the coupling on the sleeve out of gear. In this figure the shaft-coupling lever isrepresented at 72 and that for the sleeve-couplingat 73, the two levers being connected by a bar 74, provided with a catch 75, against which bears a pawl 76, connected by a cord to a lever 77 at the end of the apparatus. A helical spring 78, secured at one end 79 to the frame 62 and at the other end to the connecting-bar 74, causes the said connecting-bar to move to the left on the drawings. The pawl 76 is raised (see Fig. 9) as soon as the carriage 110 strikes the lever 77, as illustrated on the right-hand side of Fig. 11, in which figure the carriage 110 is shown twicethat is to say, on the left-hand side during the printing operation and on the right-hand side at the end of the printing operationin the moment in which the pawl 76 is raised, and in consequence of the influence of the spring 78 the shaft-coupling is thrown out and the sleevecoupling thrown into gear, thus causing the carriage to commence its return movement. At this moment the roller 80, mounted on the connecting-bar 74, bears against a verticallysliding cam provided with a projection 82 and connected by a cord to a double crank-lever 81. As soon as the carriage completes its return movement it strikes against the lever 81, whereby the cam is raised, and the projection 82 coming into contact with the roller the connecting-bar 74 is moved against the influence of the spring 78, whereby both couplinglevers are brought to the mid-position and the carriage is brought to rest. (See Fig. 10.)

After the yarn has received all its colors it is necessary to fix the coloring by steaming, and for this purpose I provide centrally between the two railways 4 a third railway 84 and a truck 83 (see Figs. 5, 6, and 7) the full length of the railways 4, and, further, in continuation of the railway 84 a steaming apparatus 85, also provided with rails, into which the truck 83, with the yarn, can be drawn for the purpose of being steamed. In order to place the yarn upon the steaming-truck 83 without touching it by hand, the shafts 2, which carry the rods 3 and, as already described, are mounted so as to be capable of being partially revolved, are provided with cranks 86 86, (see Fig. 3,) which by means of rods 87 87 are connected with spur-wheels 88 88, and if one of these last are so turned by means of a crank and pinion 89 89 as to raise the rods 3 upward toward a vertical position the yarn will fall off upon the steaming-truck 83. The threads instead of lying side by side, as upon the rods 3, will fall one on top of another, which is extremely advantageous for the distribution of the color in the yarn. At the end of the steaming apparatus is arranged a drum, which by being coupled up with gearing driven by a strap is caused to wind up a cord or wire attached to the truck, and so draw the said truck into the steaming apparatus. A cord, which is at- 90 being driven in the reverse direction the truck is withdrawn from the steaming apparatus.

The driving of the drum 90 is arranged in the following manner: Referring to Figs. 3 and 4, a spur-wheel 92 is loosely mounted on the shaft 91, upon which shaft is also mounted a sleeve 93, connected to the drum 90 by means of the spur-gear 94. The sleeve 93 is provided at its left-hand end, as seen on the drawings, with a claw-coupling sliding on a feather, which need only be coupled to the spur-wheel 92 by the movement of the forked lever 95 in order to put the said sleeve in motion. In a manner similar to the arrangement already described with reference to the printingcarriage the forked lever 95 is provided with a spring, which holds the coupling open, and a lever provided with a catch, which holds the forked lever 95 in the coupled position, and as soon as the steamingtruck has returned to its normal position it strikes against a double-armed lever arranged in similar manner, so that the horizontal member is raised, thus lifting the pawl, when the forked lever 95 under the influence of vthe spring puts the cord-drum gear out of action.

The washing of the yarn and the steamingtruck now follows. As can be seen from Fig. 7, the railway 84, upon which the steamingtruck 83 rests in the printing-machine, is not rigidly mounted, but is secured to transverse supports 109, hung upon cords 111. These cords 111 run over pulleys 112 112 and 113 113 to drums 100, Fig. 3, described below. Beneath the rails 84 is arranged a water-tank 96 in full length of the steaming-truck, so that by slackening the supporting-cords the said truck can be lowered into the water-tank. The arrangement for the paying out and hauling in of the supporting-cords is shown in Figs. 3 and 4. By turning the hand-crank 97, and thereby the spur-gear 98 99, the drums 100 100 can be caused to revolve either by the right or by the left, thus lowering the truck into the water-tank or raising it out of the same. In the water-tank, running the whole length of the same, is a shaft 101, on which are secured about every one-half meter apart a number of forks 102. As the truck is lowered into the tank the forks 102 pass between the supports upon the yarn-rests and hold the yarn in the fork while the truck is lowered to the bottom of the tank. By means of the coupling 103, Fig. 3, the shaft 91 is caused to revolve with the spur-wheel 92, and by means of the meter-wheels 104, the crank 105, and connecting rod 106 a lever 107, mounted on the shaft 101, 011 which are mounted the washing-forks, is caused to vibrate. While the said washing-forks participate in this vibrating movement, both the yarn and, facilitated by the agitation of the water, also the truck are each separately washed. As soon as the washing has continued for a sufiicient length of time the coupling 103 is thrown this invention, what I desire to secure by Letters Patent of the United States is- 1.
